I am having trouble getting Maxsea to update my position. It is recognizing my GPS, and receiving info, but just won't update my position and give me a lat/long.

I am using Maxsea V10.1.3.2 with a Royaltek RGM-3600 USB GPS on Windows XP. The newest drivers for the GPS are installed. The users manual for the GPS says it works with NMEA 0183, which is what I have selected. It also states that the baud rate is 4800, which is what I have selected. Maxsea recognizes the GPS in serial com 4, and I have selected that as my master. When I click on the utilities tab, and go down to Data input/output settings (F4) then over to the "check data" tab, there is loads of data coming through the GPS. However the program continues to tell me that it doesn't have a position. Of course I have used it in open air, on a clear day, and still no luck.

I'm working with Maxsea 11, so my screens will be somewhat different from yours, but, here's a few questions:

For your instrument, on the Data I/O Settings, is the instrument selected (checked)? Under "advanced settings" for your instrument, is the "Position" sentence selected (checked)? What "sentence" is selected?

If that all looks good, when you say there's "loads of data" coming in from the GPS, which NMEA sentences are coming across? I believe Maxsea is looking for the GLL sentence for position data.

Log the data coming from the GPS in your terminal program and look for the GLL message. The data string that you should be looking for would look like this:

Quote:

$GPGLL, 3723.2475, N, 12158.3416, W, 161229.487, A*2C

If you're not seeing that line in the data capture from the GPS with valid lat/long data, then the GPS may be defective.

If you see the data okay in the terminal program, then there may be an issue with the serial port you have it set as. Try changing which serial port it shows up as. This is probably something you can change/set in the driver.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
